  how horrible and pitiful :-( ;-)

No, it's not complicated, at all:

You disable the *.lst auto-mode (see below) and your will have
to activate sas-listing-mode by 
	    M-x SAS-listing-mode 
yourself in those cases where you still want it.

Just replace the 3 lines (line nr. 112--114) in essl-sas.el

(if (not (featurep 'xemacs))
    (setq auto-mode-alist
	(append '(("\\.[lL][sS][tT]\\'" . sas-listing-mode)) auto-mode-alist)))

by the four lines

;;NO: I hate being put in read-only sas-listing-mode for all *.lst files:
;;NO (if (not (featurep 'xemacs))
;;NO     (setq auto-mode-alist
;;NO 	(append '(("\\.[lL][sS][tT]\\'" . sas-listing-mode)) auto-mode-alist)))

---

``Of course'', the next version of ESS will have a customizable
variable that allows to turn off the automatic sas-listing-mode
more elegantly.
